SubjectRe: [RFC][PATCH] clocksource: Avoid selecting mult values that might overflow when adjusted
We've backported the patch to our kernel, and redo the test[1] that
formerly caused system stall.
After 12-hours, no system stall observed.

Chen Jie

[1] The test is just do "sleep 5 && reboot " on our mips64 compatible
CPU@500MHz. At each boot time, BIOS will calculate CPU Freq. Some CPU
Freq(around 500MHz) caused easy-overflow clock mult values in the
former tests, which then led to "sleep 5" never return.
